Abstract

PURPOSE:To enable increase in the oscillating angle of an oscillating barrel without increasing the oscillating angle of a handle in the stage of subjecting many small objects to a surface treatment with the oscillating barrel by making plural pieces of gears which transmit the oscillation of the handle to the barrel smaller from the handle side toward the barrel side. CONSTITUTION:An oscillating barrel 1 having an opening 11 in the upper part, a swelling part 12 in the bottom, and many small holes 14 on a peripheral body part 13 is used in the stage of subjecting small objects to be treated such as bolts, buttons or the like to a surface treatment such as plating, chromating treatment, etc. The barrel 1 is immersed in a treating vessel 51 contg. a treating liquid, and the cross rod part 32 of a handle 31 as its oscillation transmitting mechanism is placed between a pair of pawls 84 of a driving rod 8. The oscillating motion is transmitted, via gears 4, 5A, 5B, 18 to the barrel 1. The gear ratio in this case is made smaller from the handle 31 side toward the barrel 1 side to amplify the oscillation of the handle 31 and to transmit the same to the barrel 1, whereby the barrel 1 is largely oscillated at the small oscillating angle of the handle 31.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface treatment apparatus using a swinging barrel.

In surface treatments such as plating, chromate treatment, fender treatment, zinc-chromet treatment, etc., step 1: Fill a barrel with a porous wall with the object to be treated, immerse the barrel in the treatment solution, and rotate or shake it. A method is used in which surface treatment is performed by moving the object to uniformly contact the processing liquid with the object. In such a slot system, it is better to use a swinging barrel because the upper part of the barrel can be kept open at all times, and therefore the workpieces can be taken out and put in automatically. In addition, the processing liquid inside the barrel also enters and exits through the upper opening in addition to increasing its volume through the barrel's porous wall, making it easy to renew.Furthermore, the objects to be processed inside the barrel are easily agitated so that the upper and lower sides are interchanged, making it easier to process. It has the advantage of being evenly distributed.

For example, in the above-mentioned swing barrel system, there is a degreasing tank.

A rinsing tank, a plating tank, a rinsing tank, etc. are arranged in series 2, and a swinging barrel is carried by a transport means across each of the processing tanks,
A series of surface treatments are performed by sequentially immersing the swinging barrel in each treatment tank and swinging it. Conventionally, in order to swing the swinging barrel, the barrel frame ( The swing shaft (1!7) of the swing barrel (101') is pivotally supported on the barrel frame (+02').
A handle (1

The gear (I+8) attached to II (117) and meshing with the gear (+05) was transmitting itching to the swinging barrel (101), but the material to be processed in the swinging barrel (10+) could not be sufficiently agitated. To do this, it is necessary to increase the I-folding angle of the swinging barrel (+01). However, on the other hand, the handle (+

), (+94) to swing smoothly and without any trouble, reduce the swing width of the drive rod (+17) and adjust the handle (+31).
It is preferable that the swing angle is not too large.

As described above, the main point of the present invention is to reduce the swing angle of the swing barrel toward the larger barrel without increasing the swing angle of the handle.

If the present invention is explained by an embodiment shown in the drawings, (1)
This is a moving barrel for glazing, and its details are shown in FIGS. 3 and 4. The swinging barrel (1) has an approximately inverted heart shape in cross section in the transverse direction, an opening O1 is provided at the top, a raised portion f13 is formed at the bottom medium, and a circumferential barrel portion O1 is provided.
3 is provided with a large number of small-diameter holes to prevent the material to be processed filled in the barrel from spilling out. The barrel (1)
A rocking shaft α force is extended from the side plates QQ and C1fS of the shaft, and a gear Q→ is fitted onto one of the rocking shaft α forces. The swing axis θ is then passed over the barrel frame (2). A hollow hole 07)A is provided on one side of the swing axis α, and an electrode wire 0! is inserted into the barrel (1) from the outside through the core and the center hole α71A. '9 is inserted. Barrel frame (2) has a swing axis of 0η
A side wall plate (21) that rotatably supports the side wall plate (21), a pair of conductive support arms extending laterally from the F end of the side wall plate Qυ, @, from the -H end of the side wall plate (goods). It consists of hanging rods that extend in two directions. The electrode wire αG id is connected to one of the conductive support arms (a). A handle shaft (3) is rotatably spanned over the side wall plate Qυ, and the handle shaft (3)
The horizontal rod part 3 at one end (the handle C31 is attached to the tip of the side wall plate (21)) is rounded. A gear (4) is attached to the handle shaft (3) inside the side wall plate &11, and the gear (4) is rotatably attached to the side wall plate e21 of the barrel frame (2). (5)A, and is connected to the gear 0$ of the barrel (1) via the gear (5)B, which is coaxial with the gear (5)A. The treatment tanks 61), ω, etc. are arranged in WE rows, both ends are supported by the main body frame (6), and the barrel frame (2
), the supporting arm (a) and the handle are immersed in the barrel (1), and the hanging rod (c) of the barrel frame (2) is suspended from the transport means (7), thereby transporting the swinging barrel (1). Barrel (1
), the hanging rod (a) of the barrel frame (2) is separated from the conveying means. Along the longitudinal direction of the main body frame (6), that is, along the processing tanks 6'O9ω arranged in series, a belt-shaped support can is extended to one side, and two series of drive rods are attached to the support can. (8) and (9) are supported in parallel, and the driving rods (8> and (9) are connected to the motor (c) through the connecting rod 61'), G11), wheel plate, and ■ in a predetermined mode, respectively. , 83 make a reciprocating motion. The length of the horizontal rod portion 0 of the handle GD of the swinging barrel (1) is the length of the drive rod (8).

It is long enough to straddle (9). Drive rod (8
).

(9) indicates the position of a predetermined position (for example, the processing tank 61 for the driving rod (8)), and the processing tank ω for the driving rod (9).
A pair of claws (C), G41, are projected at the position ( ).

In the above configuration, the barrel (1) has a bolt and a button.

The objects to be treated, such as hooks, are filled and conveyed by the conveying means (7) to just above the treatment tank 51), and then lowered to the treatment tank 61.
) The barrel (1) is immersed in the processing liquid. In this state, the supporting arm of the barrel frame (2)), @ is the orbiting frame (61
) is mounted on the upper surface of the tool (as described above).Furthermore, the horizontal rod part (a) of the handle Gυ, which serves as the swing transmission mechanism of the barrel (1), is mounted on the top surface of the tool (8). It is located between a pair of claws and simply straddles the drive rod (9).

Thus, as shown in FIG. 5, the reciprocating motion of the drive rod (8) is selectively converted into a swinging motion by the handle Gl via a pair of claws, and the swinging motion is converted into a swinging motion by the gear (41). ,(5)A,
(5)B.

It is transmitted to the barrel (1) through the zero phrase. At this time, i'1 of the horizontal rod part 0 of the handle C31) which is rolled up. nails
Smooth sliding between the At this time, gear (4) and 17th wheel (
5) Gear ratio with A is 3:1, gear (5) B and gear 08)
If the ratio is 1:1, it's the handle! 3]) is 60° as shown in Fig. 8, the swinging angle of gear (4) is naturally 60°, and when gear (5>A, (5)B), the above gear The swing angle is increased by the ratio to 60° x 3 =
It becomes 180°. [7 Therefore, the oscillating angle of gear α8), that is, the barrel (1), is 180°.

The swing angle θ of the barrel (1) is related to the reciprocation of the swing rod (8), but generally it is 111890' to 180°, so in the case of Fig. 8 (the swing angle of the handle is 30°～6
It is considered to be about 0'. The swinging period of the barrel (1) is equal to the reciprocating period of the drive rod (8). The handle Gυ is not necessarily vertical when one process is completed. For example, when the handle C31) is positioned at a certain angle from the vertical position as shown in Figure 6, when performing the next process, the horizontal rod part C3 of the handle G]) comes off from between the pair of claws (C) and transmits the information. In some cases. But this.

Even in such a case, when the pair of claws (goods) move in the direction of the arrow and come to the dotted line position, according to the drawing, the left claw (to) should be moved to the horizontal rod part C.
(It moves eastward and enters between the pair of claws.

In order to ensure that the lateral rods 1 and 3 of the handle Gυ fall between the pair of claws as described above, the above deviation angle of the handle 13]) must be adjusted to a certain extent due to the inertia of the barrel (1). and the above deviation angle is the maximum]! Needless to say, even when fishing, the design requires a height such that the pair of claws contact the horizontal rod part c3z, and a swing of "4".Next, the barrel ( 1) is pulled up from the processing tank 61) by the transport means (7) and immersed in the processing tank ω.In the +!L tank ω, the barrel (1)
The stem part of the handle (31) is located between the pair of claws of the drive lever (9), and simply straddles the pair 17 of the drive lever (8).

The barrel (1) is thus selectively swung by the reciprocating movement of the drive rod (9). Therefore, the ripe egg o shi51),
■Set the reciprocating period and reciprocating period suitable for each, l11, Ii, 9
If this is applied to each of the rods C81 and (9), the barrel (1) will swing in a mode suitable for each treatment in the treatment tanks (51) and 52. If either of the treatment tank 61) and ω is plated, the conductivity of the track frame 61) is connected via the support arm @ to the electrode wire (19 as the treatment tank 61),
A positive electrode plate is immersed in contact with the inner wall of one of the tanks.

To give an example of the oscillation mode, in the case of the most typical decorative plating, there is grease → water washing - copper hydride plating → water washing - nickel plating →
Two types of oscillation modes are required in the water washing line, and in accordance with this, two types of drive rods are provided as in the above embodiment. One of the oils is 5 sho + i1 cycle oscillation - 10 seconds stop → 5 seconds IR
